Shopbot "Jerking" After 3 minutes of use
Ok, last week, i replace my usb control card, because it went bad. Shop bot is back up and going... but ever 3 minutes, it jerks and stutters (all 3 axis).... Ill close out the SB program, open it... works fine for 3 min.
Ive changed usb cords, computers etc....
It may be worth noting, I have upgraded to the newest software before i replace the usb control card, just as a diagnostic step. Any help much appreciated

Did you update the firmware also? Even though it worked, it would be a good thing to do. UI (utilities install) will get you started. Also, make sure you have nothing running in the background on the PC, no screensavers, no programs checking for updates including Windows. Turn off USB selective suspend in the power plan options.
Do a packet-et test to see if your PC/USB is up to the task. Help/notes on diagnostic or UT should bring up the doc on how to test and what to look for. After running the test move, look at UD to see the results.
Is this a standard or alpha?

I just had a similar problem when I replaced mt usb card and found out it was a grounding problem. It would jerk at the same time no matter what file I would run. 2 different control boxes.

I had to run a new ground wire

From the new control box?
-
Or you replaced the main power cord?

between the shopbot and control box

Any way you can send a pic?
